WINGJOINT CONNECTION.

Specication of Letters Patent. Patented Dec., 12, 119113@ Applicationfiled December 16, 1913. Serial No. 906,981.

Kane and State of Illinois, have invented certain new and usefulImprovements in Swing-Joint Connections, of which the following is aspecification.

This invention relates to improvements in swing joint connections, andhas for its principal object to provide an improved passage for water,steam, compressed air or the like',

between adjacent cars of a train or engine and tender or the like. l

Prior to this time a rubber hose connec tion has been used almostexclusively in connectlng the steam, water, and alr pipes carried byadjacent cars, locomotives and the like and it has been found that suchconnecti'ons frequently burst under pressure and that the nipples andcouplings blow out of the rubber, thereby delaying trains, causinglserious accidents and resulting in a great waste, since the rubberconnectlon when 1t becomes defective must be thrown away and sold forscrap.

The object of our invention is to provide a metallic connection withswing joints to insure flexibility, which will be a permanent connectionand which will be capable of repairs.

A further object is to provide a metallic swing joint connection whichpossesses flexibility and which may be readily adjusted to a wide rangeof positions adjacent the end of a car.

Still another object is' to provide. an adaptable metallic connectionwhich will be substantially free of leaks.

t@ @ur invention Imay comprise two separate and similar sets ofconnected swing joints,

each set -being connected at one end to and carried by the pipe line ofa car or the like and provided at the other end with a suitable couplingby means of which the two sets are coupled together thereby forming acommunication between the pipe lines of adjacent cars.

Referring to the drawings: Figure 1 shows a side elevation of ourimproved swing joint connection showing the pipe lines oftwo adjacentcars connected by means thereof; Fig. 2 shows a top plan view of thesame; Fig. 3 shows a sectional View m5 taken on line 3-3 of Fig. 2looking in the direction of the arrows; Fig. 4 shows a secing ina valve11 at the end of each car.I

Communicating with valve 11 by a suitable elbow 11, and dependingdownwardly therefrom, is a pipe section forming a duct member 12externally threaded at 13 to engage said elbow and provided. at itslower end with an external peripheral shoulder 14, having an upperbeveled surface 15. .l ournaled upon the duct member 12 and carriedthereby is la couplingsleeve 16 externally threadedat 17 and providedwith a portion 18 adapted to be engaged by a wrench or the like. Thecoupling sleeve 16 is chamfered at its lower extremity to for ma surface19 adapted to seat upon the surface 15 on said duct member and form asteam, air, and water-tight contact therewith. At the end opposite saidsurface 19, and surrounding the duct member 12, the coupling sleeve 16is provided with a packing chamber 20 illed with a suitable packingmaterial 21 and closed at its upper end by a packing gland 22 which isjournaled upon the sleeve 12 and provided with an annular shoulder 23adapted to seat upon the upper end of said coupling sleeve when thegland is in its lowermost position. Fitting over the gland 22 is apacking nut 24 apertured to pass over said duct member and internallythreaded to engage the externally threaded portion 24: of the couplingsleeve 16. llt will be obvious that by tightening the packing nut 24 onthe coupling sleeve 16, the packing gland 22 will be forced downwardlyinto the chamber 20 thereby compressing the packing material 21 andpreventing any leakage between the duct member 12 and-the couplingsleeve 16 which revolves thereon. As above stated, leaka e is furtherprevented by the surface 19 o the coupling sleeve seating closelyupon-the surface 15 of the duct member 12.

The hollow connecting member 25 has two threaded apertures 26 and 27vthrough bosses on opposlte sides ot said member and diagonally opposedto each other. By means of the threaded aperture 26 this connectingengaging the pipe section 30 at member engages the threaded portion 17of the coupling sleeve 16, thereby forming a communication between theduct member 12 and a second duct member 12a which is car- .ried by andjournaled in the cou ling sleeve 16El having an externally threa edportion 17a engaging the threaded aperture 27 in said connecting member.vThe second duct member 12a which is in all respects similar to thefirst duct member 12, is then offset from the duct member 12 while theiraxes are substantially parallel. It is obvious that the duct member 12ais capable of rotation about its own axis within the coupling sleeve1611 and that it is also capable of bodily rotation about the axis ofduct member 12. The coupling sleeve 16a is provided with a packingchamber 20a, filled with packing material 21a and closed by a packinlggland 22 and carries a packing nut 24a. ll of these parts are in allrespects similar to the coupling sleeve and its parts carried by thefirst duct member 12.

The duct member 128L is threaded at its lower end, as shown at 13a toengage an elbow7 28. The other end of this elbow threadedly engages thethreaded portion 13b of the third duct member 12b which is disposedsubstantially at right angles to the second duct member 12". The ductmember 12b is in all respects similar to duct members 12 and 12a and ithas journaled thereon a third coupling sleeve 16b which is provided witha packing chamber 20h, containing packing material 21", closed by apacking gland 22h, and carries a packing nut 24", all of these elementsbeing in all respects similar to the previously described elementscarried by the duct member 12.

The externally threaded portion 17 b of the coupling sleeve 16b engagesan elbow 29. The aperture at the other end of the elbow 29 threadedlyengages a pipe section 30 which is disposed substantially at rightangles to the duct member 12b. Threadedly the end opposite the elbow 29,is a coupling 31 having a duct 32 therethrough. This coupling 31 isadapted yto connect with a corresponding coupling carried by the swingjoint connector of an adjacent car, as shown in Figs. 1 and 2, thusforming a complete passage for water, steam, air or the like between thepipe lines vof adjacent cars.

It will be apparent from the foregoing description that the coupling 31carried by the pipe section 30 is capable of rotation in a verticalplane about the duct member 12". It is also obvious that the coupling31, together with the duct member 12b ma both be revolved in asubstantially horlzontal plane about the axis of the member 12a. It isfurther apparent that the duct member 12a and all the parts carriedthereby may be rotated bodily about the fixed duct member externally 12.These three similar joints, formed by the members 16, 16a and 16",capable of revolving on the duct members 12, 12 and 12b respectively,make it possible to readily adjust the coupling 31 to lie in any planeand to occupy a wide range of positions adjacent the end of the car sothat the coupling 31 may readily be brought into engagement with thecorresponding coupling carried by the adjacent car.

We have thus described, in considerable detail, the essential featuresof a swing joint connection which is readily adjustable and capable ofbeing repaired in case any of the par'ts become defective. It will beunderstood, however, that we do not limit ourselves to the particulardetails of construction herein shown, since our invention may beembodied in other structures of widely divergent form.
